Wedding Invitation Printing Costs????

I’m trying to figure out the most cost effective way to print our wedding invitations. My sister-in-law ended up switching her wedding theme 4 different times before deciding on the theme she actually went with…. Since that happened she ended up having black white invitations that she purchased for one theme and never used. It’s plenty of paper for our invitations and is just very simple white paper with an eyelet lace design on the bottom, that is very fitting for our Rustic-Chic wedding next June. My question is, what would be the most cost effective way to have our invititations printed on this paper??? Going to a printing company, doing it at home, or somewhere like Staples?? I’d hate to waste this paper, especially when it’s enough for what I need and we can always “dress it up” with some twine or burlap bows.

I went to Office Max: For about 50 invites (including invite itself, directions, etc.), total was between $25.00 and $30.00. FYI: When we tried contacting Staples, they said they could not print invites smaller than a certain size. The employee at Office Max was a pro about formatting, sizing, etc. It was worth it for us!
